Resumo
The present study evaluated the influence of an optical fiber laser surface treatment process on
the tribological behaviour of the ISO 5832-1 austenitic stainless steel (SS) on the coefficient of
friction and coefficient of wear in ball-cratering wear tests. For comparison reasons, surfaces
non treated by laser were also evaluated. A phosphate buffer solution (PBS) was used as
electrolyte. Samples of this biomaterial were treated by alternating the laser frequency in order
to find out a condition that improves its tribological behaviour. Micro-abrasive wear tests were
carried out with a ball of AISI 316L SS (diameter of 25.4 mm – 1”), used as counter-body, and
abrasive slurries prepared with abrasive particles of Al2O3 and distilled water. The sample’s
surfaces finishing were analyzed by optical and electronic (SEM-EDX) microscopy. The surface
characterization showed microstructure modification due to the high temperatures involved in
the laser process and the micro-abrasive wear results indicated that the tribological behaviour is
influenced by the frequencies values used for the laser surface treatment.
